Abstract

PURPOSE: To achieve saving of energy and to make the variation characteristics of fan voltage adjustable, by constituting a fan-speed controlling circuit such that the speed, operation and stoppage of a fan is controlled by amplifying the output of a room-temperature sensor between a maximum and a minimum set voltages and comparing the same with a reference voltage.
CONSTITUTION: A voltage of a thermistor 1, higher than the voltage of a minimum voltage setting circuit 12 but lower than a set voltage of a maximum voltage setting circuit 8 via an amplifying circuit 9, is applied to an input terminal B of a comparison circuit 13. Therefore, if the room temperature becomes higher than a set temperature during cooling operation, voltage at the input terminal B of the comparison circuit 13 is raised, so that a fan driving circuit 16 is ignited at an advanced phase and a fan 17 is operated at a high speed under a maximum voltage. However, when the room temperature is lowered to the set temperature, the fan is operated under a minimum voltage and it repeats operation and stoppage by the function of a stop circuit 19 within a set temperature range of the stop circuit 19. By thus controlling the fan speed, it is enabled to achieve saving of energy and to make the variation characteristics of the fan voltage adjustable.
